make your game more playable and less payable. Maybe then it would succeed.

Since I've updated to Android 15, the game frequently crashes after watching the ads. Worst part I lose the reward cause the auto save doesn't kick in fast enough. Very frustrating. EDIT: Heyyy, they finally fixed the bug, after 4 months. Thanks! Gonna update the score

It's a time waster and a poorly thought out one as well. the "end game" prestige system is just laughable compared to the developer's other games. boy, it suuurre is fun starting over from the beginning and redoing everything but SLOWER(like... way slower. 100 times slower).

I enjoy this game and anything made by this publisher. Honestly it's becoming a problem. Don't find other games near as entertaining.
